此程序是关小波包分解的中值滤波器的图像去噪程序-this procedure is concerned wavelet packet median filter image denoising procedures

包滤波器，主要功能是在给定的滑动窗口大小下，对每个窗口内的像素值进行相加求和-Packet filter, the main function is given under the sliding window size for each window of the pixel values ​ ​ summed

压缩包内包含两个m文件，一个是直方图均衡化，另一个是频域滤波，即对一幅图像进行低通、高通滤波，并且使用高频强调和直方图均衡相结合的方法增强图像；另外包含了四张测试用的图片。(Compressed packet contains two m files, one is histogram equalization, the other is a low pass filtering in frequency domain, i.e., images of a high pass filter, a
